SNAP-FASTENER.

Specification of Letters Patent.

Patented May 15, 1906.

To all whom it may concern:

Be it known that I, FRANK E. WARNER, a

citizen of the United States, residing at Wa terbury, in the county of New Haven and State of Connecticut, have invented a certain new and useful Improvement in Snap- Fasteners, of which the following is a full, clear, and exact description.

This invention relates to that class of separable garment-fasteners in which a resilient socket member is employed.

The resiliency of such socket members lacks a degree of permanence which greatly impairs the usefulness and salability of such members; and the object of this invention is to produce a socket having a practically reinforced resiliency.

The invention consists of a socket member having a stud-opening surrounded by a studengaging device folded upon itself, arranged at a flare and slitted radially through the fold, all as I will proceed now more particularly to set forth and finally claim.

In the accompanying drawings, illustrating the invention, in the several figures of which like parts are similarly designated, Figure 1 shows in cross-section, in three views reading down, the cap, tubular dome, and socketpiece, respectively, of one form of the invention. Fig. 2 is a cross-section of these parts assembled and secured to a piece of fabric. Fig. 3 is a bottom plan view of the socketpiece detached. Fig. 4 is a top lan view of the socket-piece. Fig. 5 is a si e elevation, and Fig. 6 is a cross-section, of the socket of the preceding figures. Fig. 7 shows in cross section, in three views reading down, the cap, dome, and socket-piece, respectively, of another form of the invention. Fig. 8 is a crosssection of the parts of Fig. 7 assembled and applied to a piece of fabric. Fig. 9 is an elevation, and Fig. 10 is a cross-section, of the socket of Figs. 7 and 8.

In both forms of the invention herein shown substantially the same construction of socket-piece is used, and this socket-piece comprises a base 1, provided with a central opening 2 for the passage into and out of the socket of the head or stud of the fastening,

and it may be said here that any preferred form of head or stud may be used in connection with the socket, provided it is constructed with some sort of neck of smaller diameter than the largest diameter of the head, so that as the head passes into and out of the socket the socket member will yield, and. as the head or stud passes into the socket the yielding portion of the socket will extend into the neck to engage the head or stud securely. Surrounding this opening the material of the base 1 is bent upwardly and flared or inclined outwardly and folded upon itself so as to form the standing fold member 3 and the free fold member 4, the latter having an inwardly-projecting lip 5, and this lip is the immediate element hereinabove referred to for directly engaging the neck of the head or stud. The fold is provided with a number of slits, preferably four, and designated 6. The base 1 is provided with a peripheral flange 7, bent over the lower edge of the dome 8, so as to unite the socket-p1ece and dome, as in Figs. 5 and 6, and this dome is provided with a tubular extension 9, which constitutes the fastening medium for passing through a hole in the article 10 from one side and entering the fastening-cap 11 on the other side of the article.

As shown in Figs. 1 and 2, the cap 11 comprises an outer shell 12, provided with an anvil-piece 13 and a centrallyerforated collet 14, the anvil-piece and co let being united with the shell by flanging the shell over them.

The application of the fastening-cap hereinabove described is as is well known-that is to say, the tubular-portion 9 of the socket serves as a sort of eyelet or rivet, which being forced into the cap through the opening in the collet encounters the anvil, and its edge is spread or clenched about the anvil, substantially as shown in Fig. 2.

Instead of applying to the socket-piece a dome with a tubular extension the invention is susceptible of use in connection with a dome 15, Figs. 7, 8, 9, and 10, which has no tubular extension, but instead has a hole 16.

This form of socket may be fastened to fabric by a cap comprising a shell 17, a collet 18, and a two-pronged rivet 19, secured between the shell and collet and adapted to enter the hole 16 in the dome and be clenched within the dome, as shown in Fig. 8.

It is to be observed that the stud-engaging device is made integral with the base, and, further, that the free fold member is a continnation of the metal ofthe standing fold member returned downwardly or outwardly with in the standing fold member and extending not lower than the plane of the base.-

In both forms of" the invention the studber, but extends also into the standing fold member, and" thus the free fold member is reinforced and the pennanenoeof the resilience ispractically insured.

What It claimis- 1. A. snap fastener socket-piece, provided withia base having'a centralopening'for the passage of the header stud, said-openingsur rounded by av stud-engaging: resilient fold comprising a flared standing fold member and. an inturned outwardly projecting free fold" member, and means to secure the socket piece to anarticle.

2. A snap-fastener, having: a socket-piece provided with a centralopening for the passage of the head or stud, said opening surrounded by a stud-engagingrdevice composed of a flared st'andingfold member and an in:-

turned outwardly-projecting free fold member slitted radially, said free I fold member having an inwardly-projecting lip and means toattaoh t'he socket-piece to an article.

3. A snap-fastener, having a socket-piece composed of'a base having a central opening for the passage of the head or stud, said opening surrounded by a stud-engaging devicecomposed of a flared standing fold member and a free fold member slitted radially, the fold members being integral with the base, and the free fold member having an inwardly-proj ecting lip.

4. A snap-fastener, having a socket-piece provided with a central opening for the passage of the head or stud, said opening surrounded-by a studengaging device composed of a flared standing fold member and a free fold member slitted radially, said free fold member having an inwardly-projecting lip, a dome attached to said socket-piece, a fastening-cap and means to connect the dome and fastening-cap.

In testimony whereof I have hereunto set my hand this 21st day of July, A. D. 1905. FRANK E. WARNER. Witnesses:
